Akasa Amber 12cm question

[squiffy]

Just picked up a Akasa Amber 12cm to replace the Thermaltake Thunderblade, just wondering is it safe to power this fan off my motherboard header chassis fan, or should I just use the molex connector?

0.18A, 2.16W

ok, is the supplied molex to 3 pin connector come with a RPM sensor wire?, or is that the power wire? Or both? It has the outer two wires (middle is missing)

4 pin molex doesn't support RPM monitoring.

The fan itself is 3 pin, but suppled with the fan is a 3 pin female to 4 pin molex to 2 wire (3 pin) mobo fan header. So do you use the molex for power and the 3 pin for rpm, or don't use the molex and use 2 pin to mobo for power and RPM?
